DETAILED DESCRIPTION

As described in this document, embodiments are directed to a game controller for a mobile device with a hold-open feature.

Keeping the handles pulled apart while inserting the mobile device into a game controller can be difficult. For example, a user holding a mobile device in the user's right hand may need to use the user's left hand to pull the two handles apart when placing the mobile device between the two handles of the game controller. This difficulty with insertion may be exacerbated when the game controller connects to the mobile device via a connector, such as USB-C connector, because the user must also ensure that the mobile device is aligned with the connector when inserting it. The removal of the mobile device may be equally vexing as the user must once again attempt to pull the two handles apart with one hand.

But in embodiments of the disclosed game controller, once the handles are pulled apart sufficiently, the handles lock in place, allowing the user to easily insert the mobile device. Then, by applying light pressure on the handles, the user can unlock the handles and snap the device shut, securing the mobile device to the game controller.

With regard to terminology used in this disclosure, it is noted that the “first” and “second” designation is largely arbitrary, meaning, for example, that the choice of which of the two handles is the “first handle” and which is the “second handle” is not critical unless the context requires otherwise. Hence, while the drawings illustrate the second handle 102 as being on the right side of the game controller 100 and the first handle 101 as being on the left side of the game controller 100, it could also be that the handle designated as being the second handle 102 is on the left side of the game controller 100 and the handle designated as being the first handle 101 is on the right side of the game controller 100. For that reason, features that are described in this Detailed Description as being on the “second handle,” for example, may be claimed as being on the “first handle” to avoid the potentially confusing situation of reciting a “second” without a “first.”

FIG. 1 is a perspective view showing portions of a game controller 100, according to embodiments. As illustrated in FIG. 1, a game controller 100 may include a first handle 101, a second handle 102, and a bridge 119. Each of the first handle 101 and the second handle 102 is configured to contact and support a mobile device 199, though not all contemplated embodiments will include the second handle 102. An exemplary mobile device 199 is shown in broken lines to illustrate how the game controller 100 may contact and support a mobile device 199 in some embodiments. The mobile device 199 may be, as examples, a smartphone or a tablet computer.

As illustrated in FIG. 1, the first handle 101 includes a guide portion 113 and a main body portion 105. The guide portion 113 extends from the main body portion 105 and along a first end 115 of the span 120 of the bridge 119. (See also FIGS. 5 and 6.) The guide portion 113 of the first handle 101 is configured to align the bridge 119 with the main body portion 105 of the first handle 101.

As illustrated, the first handle 101 includes a user-accessible, first hardware interface 103 on the main body portion 105 of the first handle 101. The first hardware interface 103 could be a button, an analog stick, a touchscreen, a touchpad, a knob, a slider, a switch, a wheel, a dial, a directional pad, or another such feature configured to accept touch inputs from a user's finger or a stylus. As shown in FIG. 1, the first hardware interface 103 may include multiple such hardware interfaces.

Likewise, the second handle 102 includes a guide portion 114 and a main body portion 106. The guide portion 114 extends from the main body portion 106 and along a second end 116 of the span 120 of the bridge 119. (See also FIGS. 5 and 6.) The guide portion 114 of the second handle 102 is configured to align the bridge 119 with the main body portion 106 of the second handle 102.

As illustrated, the second handle 102 further includes a user-accessible, second hardware interface 104 on the main body portion 106 of the second handle 102. As above for the first hardware interface 103 of the first handle 101, the second hardware interface 104 could be a button, an analog stick, a touchscreen, a touchpad, a knob, a slider, a switch, a wheel, a dial, a directional pad, or another such feature configured to accept touch inputs from a user's finger or a stylus. The second hardware interface 104 may include multiple such hardware interfaces, as illustrated in FIG. 1.

One or both of the first handle 101 and the second handle 102 may include a connector 125 for physical and electrical connection to the mobile device 199. The connector 125 may be, for example, a USB-C connector.

FIGS. 2-4 are top views of the game controller 100 of FIG. 1, showing an example process of how the game controller 100 may contact and support an example mobile device 199. As illustrated in FIG. 2, the mobile device 199 may be placed over the bridge 119, between the first handle 101 and the second handle 102 of the game controller 100. As illustrated in FIG. 3, the connector 125 of the game controller 100 may be joined with a corresponding connector on the mobile device 199. FIGS. 2 and 3 show examples of an extended configuration of the game controller 100. In FIG. 4, the mobile device 199 is secured between the first handle 101 and the second handle 102 of the game controller 100. FIG. 4 illustrates an example of a retracted configuration of the game controller 100. The extended configuration and the retracted configuration of the game controller 100 will be described in more detail below. The reader will note, though, that there is more than one retracted configuration. For example, FIG. 4 illustrates an example of a retracted configuration when the game controller 100 is securing a mobile device 199. As another example, FIG. 5 (described below) illustrates an example of a retracted configuration when the game controller 100 is not securing a mobile device 199.

FIG. 5 is a front, partial sectional view of the game controller 100 of FIG. 1 in an example of a retracted configuration of the game controller 100. FIG. 6 is a front, partial sectional view of the game controller 100 of FIG. 1 in an example of an extended configuration of the game controller 100. As illustrated in FIGS. 5-6, a game controller 100 may include a first handle 101, a second handle 102, and a bridge 119, each as described above for FIGS. 1-4. In each of FIGS. 5-6, external portions of the first handle 101, the second handle 102, and the bridge 119 are not shown to make certain internal features visible.

As illustrated, the bridge 119 is in sliding engagement with the first handle 101. As illustrated, the bridge 119 is not telescoping, meaning that segments of the bridge 119 do not slide within another segment of the bridge 119 to allow for lengthening or shortening of the bridge 119. The bridge 119 has a span 120 extending away from the main body portion 105 of the first handle 101, and the span 120 has a transverse midline 121.

The bridge 119 and the first handle 101 are configured to allow the main body portion 105 of the first handle 101 to translate in a retraction direction 122 toward the midline 121 of the bridge 119 and into a retracted configuration, such as one of the example retracted configurations illustrated in FIG. 4 or 5. The bridge 119 and the first handle 101 are configured to allow the main body portion 105 of the first handle 101 to also translate in an extension direction 123 away from the midline 121 of the bridge 119 into an extended configuration, such as one of the example extended configurations illustrated in FIG. 2 or 6.

As used in this disclosure, the transverse midline 121 of the bridge 119 is a reference datum used to define the extension direction 123 and the retraction direction 122. That is, the retraction direction 122 is toward the transverse midline 121, while the retraction direction 122 is away from the transverse midline 121. Accordingly, the transverse midline 121 of the bridge 119 may or may not coincide with a physical structure on the game controller 100.

Likewise, the bridge 119, as illustrated, is in sliding engagement with the second handle 102, and the span 120 of the bridge 119 extends away from the main body portion 106 of the second handle 102. The bridge 119 and the second handle 102 are configured to allow the main body portion 106 of the second handle 102 to translate in the retraction direction 122 toward the midline 121 of the bridge 119 and into the retracted configuration. The bridge 119 and the second handle 102 are configured to allow the main body portion 106 of the second handle 102 to also translate in the extension direction 123 away from the midline 121 of the bridge 119 into the extended configuration.

As illustrated in FIGS. 5-6, the game controller 100 may also include a first spring mechanism 107, a second spring mechanism 108, a first latch mechanism 109, a second latch mechanism 110, a first linear rack 111, a second linear rack 112, and a pinion 124. These are described below.

The first spring mechanism 107 is configured to bias the first handle 101 toward the retracted configuration. In addition, the first spring mechanism 107 exerts a first retraction force on the first latch mechanism 109 in the retraction direction 122. As illustrated, the first spring mechanism 107 may be attached to the first handle 101 through a shaft 117 and is also attached to the bridge 119. The first spring mechanism 107 may be or include a first constant-load spring connecting the first handle 101 to the bridge 119. The first constant-load spring is configured to exert a substantially constant force on the first handle 101 in the retraction direction 122. As used in this disclosure, “substantially constant” means largely or essentially invariable, yet without requiring perfect constancy, as the game controller 100 transitions from the retracted configuration to the extended configuration and from the extended configuration to the retracted configuration.

The second spring mechanism 108 is configured to bias the second handle 102 toward the retracted configuration. In addition, the second spring mechanism 108 exerts a second retraction force on the second latch mechanism 110 in the retraction direction 122. As illustrated, the second spring mechanism 108 is attached to the second handle 102 through a shaft 118 and is also attached to the bridge 119. The second spring mechanism 108 may be or include a second constant-load spring connecting the second handle 102 to the bridge 119. The second constant-load spring is configured to exert a substantially constant force on the second handle 102 in the retraction direction 122.

The first latch mechanism 109 is configured to temporarily lock the bridge 119 in the extended configuration. The first latch mechanism 109 is further configured to require a first disengagement force in the retraction direction 122 to unlock the bridge 119 from the extended configuration. The first disengagement force is greater than the first retraction force exerted by the first spring mechanism 107 in the retraction direction 122. The additional force (that is, that portion of the first disengagement force that exceeds the first retraction force) may be provided by, for example, pressure from the user's hands exerted in the retraction direction 122.

Likewise, the second latch mechanism 110 is configured to temporarily lock the bridge 119 in the extended configuration. The second latch mechanism 110 is further configured to require a second disengagement force in the retraction direction 122 to unlock the bridge 119 from the extended configuration. The second disengagement force is greater than the second retraction force exerted by the second spring mechanism 108 in the retraction direction 122. The additional force (that is, that portion of the second disengagement force that exceeds the second retraction force) may be provided by, for example, pressure from the user's hands exerted in the retraction direction 122.

As illustrated, the first linear rack 111 is coupled to the first handle 101 and is in sliding engagement with the bridge 119. The first linear rack 111 extends substantially along the span 120 of the bridge 119. As used in this disclosure, “substantially along” means largely or essentially in the direction of, without requiring perfect conformity. The first linear rack 111 may further include a step 126 or indentation, which may engage with the first latch mechanism 109 as described more fully below. As used in this disclosure, “to engage” means “to interlock with; to fit together.”

The second linear rack 112 is coupled to the second handle 102 and is in sliding engagement with the bridge 119. The second linear rack 112 extends substantially along the span 120 of the bridge 119. The second linear rack 112 may further include a step 126, which may engage with the second latch mechanism 110 as described more fully below.

As illustrated, the pinion 124 is affixed to the bridge 119. The pinion 124 is in contact with each of the first linear rack 111 and the second linear rack 112. The pinion 124 is configured to rotate relative to the bridge 119 as the first linear rack 111 is translated relative to the pinion 124. The pinion 124 is also configured to rotate as the second linear rack 112 is translated relative to the pinion 124.

FIG. 7 is a close-up of a portion of the game controller 100 of FIGS. 5 and 6, illustrating an example latch mechanism in an unlatched configuration. FIG. 8 is a close-up of a portion of the game controller 100 of FIGS. 5 and 6, illustrating the example latch mechanism of FIG. 7 in a latched configuration. While illustrated and described for the first-handle side of the game controller 100, the discussion for FIGS. 7 and 8 applies equally to the second-handle side of the game controller 100. Hence, the example latch mechanism of FIGS. 7 and 8 may be the first latch mechanism 109 described above for FIGS. 5 and 6, the second latch mechanism 110 described above for FIGS. 5 and 6, or both the first latch mechanism 109 and the second latch mechanism 110.

As illustrated in FIGS. 7 and 8, the example latch mechanism may include a catch 127 coupled to the bridge 119. The catch 127 is configured to contact and engage the step 126 on the first linear rack 111 in the extended configuration and disengage from the step 126 on the first linear rack 111 in the retracted configuration. To facilitate the engagement and disengagement of the catch 127 from the step 126, the step 126 may be angled or rounded, or a portion of the catch 127 facing the step 126 may be angled or rounded, or both.

As illustrated, the catch 127 is coupled to the bridge 119 through a pivot 128. The first latch mechanism 109 may also include a cantilevered spring 129 configured to apply a torque to the catch 127 about the pivot 128 to bias the catch 127 against the first linear rack 111. The cantilevered spring 129 may be coupled to the bridge 119 by one or more attachment points 130.

With particular reference to FIGS. 2-8, in use the game controller 100 may initially be in a retracted configuration, such as the retracted configuration illustrated in FIG. 5. In the retracted configuration, the catch 127 is disengaged from the step 126 on the first linear rack 111. In versions having a catch 127 on a second linear rack 112 (also or instead of the catch 127 on the first linear rack 111), in the retracted configuration, the catch 127 is disengaged from the step 126 on the second linear rack 112.

Then, the user may apply a force (using, for example, the user's hands) to the first handle 101 or the second handle 102, or both, in the extension direction 123 to move the game controller 100 into an extended configuration, such as the extended configurations illustrated in FIGS. 1, 2, and 6. In other words, the user may pull the first handle 101 and the second handle 102 apart from each other.

In transitioning to the extended configuration, the first linear rack 111 slides relative to the catch 127 for the first end 115 of the span 120 until that catch 127 is aligned with the step 126 in the first linear rack 111. During the transition, the first spring mechanism 107 continues to bias the first handle 101 toward the retracted configuration and exerts a first retraction force on the first latch mechanism 109 in the retraction direction 122. The cantilevered spring 129 then causes the catch 127 for the first end 115 of the span 120 to engage the step 126 of the first linear rack 111 by forcing the catch 127 into the step 126. The first latch mechanism 109 is now temporarily locking the bridge 119 in the extended configuration by way of the catch 127.

In versions having a catch 127 on a second linear rack 112 (also or instead of the catch 127 on the first linear rack 111), in transitioning to the extended configuration, the second linear rack 112 slides relative to the catch 127 for the second end 116 of the span 120 until the catch 127 is aligned with the step 126 in the second linear rack 112. During the transition, the second spring mechanism 108 continues to bias the second handle 102 toward the retracted configuration and exerts a second retraction force on the second latch mechanism 110 in the retraction direction 122. The cantilevered spring 129 then causes the catch 127 for the second end 116 of the span 120 to engage the step 126 of the second linear rack 112 by forcing the catch 127 into the step 126. The second latch mechanism 110 is now temporarily locking the bridge 119 in the extended configuration by way of the catch 127.

With the bridge 119 temporarily locked in the extended configuration, the user may then insert a mobile device 199 into the game controller 100 by placing the mobile device 199 over the bridge 119, such as illustrated in FIG. 2. If necessary, the connector 125 of the game controller 100 may then be joined with a corresponding connector on the mobile device 199, such as illustrated in FIG. 3.

To unlock the hold-open feature, where the bridge 119 is temporarily locked in the extended configuration, and return the game controller 100 to a retracted configuration, the user typically applies a force to the first handle 101 in the retraction direction 122. This user-applied force, coupled with the first retraction force exerted by the first spring mechanism 107, causes the catch 127 for the first end 115 of the span 120 to disengage from the step 126 in the first linear rack 111. Once disengaged, the first retraction force exerted by the first spring mechanism 107 causes the game controller 100 to transition to a retracted configuration.

In versions having a catch 127 on a second linear rack 112 (also or instead of the catch 127 on the first linear rack 111), the user may apply a force to the second handle 102 in the retraction direction 122. This user-applied force, coupled with the second retraction force exerted by the second spring mechanism 108, causes the catch 127 for the second end 116 of the span 120 to disengage from the step 126 in the second linear rack 112. Once disengaged, the second retraction force exerted by the second spring mechanism 108 causes the game controller 100 to transition to a retracted configuration.

Since moving the game controller 100 from the retracted configuration to the extended configuration is often done by using both of the user's hands (such as, for example, one hand on each of the first handle 101 and the second handle 102), the hold-open feature allows the user—once the game controller 100 is temporarily locked in the extended configuration—to remove one or both of the user's hands from the game controller 100 (such as, for example, from either the first handle 101 or the second handle 102, or both) to manipulate the mobile device 199 into position, such as the position illustrated in FIG. 2. Hence, embodiments of the disclosed technology allow the user to efficiently and easily insert and remove a mobile device 199 from the game controller 100.

FIG. 9 is a close-up of a portion of an alternative arrangement for the game controller 100 of FIGS. 5 and 6, illustrating an example latch mechanism in an unlatched configuration. FIG. 10 is a close-up of a portion of an alternative arrangement for the game controller 100 of FIGS. 5 and 6, illustrating the example latch mechanism of FIG. 9 in a latched configuration. While illustrated and described for the first-handle side of the game controller 100, the discussion for FIGS. 9 and 10 applies equally to the second-handle side of the game controller 100. Hence, the example latch mechanism of FIGS. 9 and 10 may be the first latch mechanism 109 described above for FIGS. 5 and 6, the second latch mechanism 110 described above for FIGS. 5 and 6, or both the first latch mechanism 109 and the second latch mechanism 110.

As illustrated in FIGS. 9 and 10, the example latch mechanism may include a tension spring 132 coupled to the bridge 119. An engagement portion 131 of the tension spring 132 is configured to contact and engage the step 126 on the first linear rack 111 in the extended configuration and disengage from the step 126 on the first linear rack 111 in the retracted configuration. To facilitate the engagement and disengagement of the catch 127 from the step 126, the step 126 may be angled or rounded.

As illustrated, the tension spring 132 is coupled to the bridge 119 through one or more attachment points 133. The tension spring 132 is configured to bias the engagement portion 131 of the tension spring 132 against the first linear rack 111. The engagement portion 131 is configured to engage the step 126 in the extended configuration.

Accordingly, in transitioning from the retracted configuration (an example of which is illustrated in FIG. 9) to the extended configuration (an example of which is illustrated in FIG. 10), the first linear rack 111 slides relative to the engagement portion 131 of the tension spring 132 until the engagement portion 131 is aligned with the step 126 in the first linear rack 111. The tension spring 132 then causes the engagement portion 131 to engage the step 126 of the first linear rack 111 by forcing the engagement portion 131 into the step 126. Likewise, in transitioning from the extended configuration to the retracted configuration, the engagement portion 131 of the tension spring 132 is disengaged from the step 126 in the first linear rack 111. Otherwise, operation of this example latch mechanism is substantially as described above for FIGS. 2-8.

FIG. 11 is a close-up of a portion of an alternative arrangement for the game controller 100 of FIGS. 5 and 6, illustrating an example latch mechanism in an unlatched configuration. FIG. 12 is a close-up of a portion of an alternative arrangement for the game controller 100 of FIGS. 5 and 6, illustrating the example latch mechanism of FIG. 11 in a latched configuration. While illustrated and described for the first-handle side of the game controller 100, the discussion for FIGS. 11 and 12 applies equally to the second-handle side of the game controller 100. Hence, the example latch mechanism of FIGS. 11 and 12 may be the first latch mechanism 109 described above for FIGS. 5 and 6, the second latch mechanism 110 described above for FIGS. 5 and 6, or both the first latch mechanism 109 and the second latch mechanism 110.

As illustrated in FIGS. 11 and 12, the example latch mechanism may include a catch 134 coupled to the bridge 119. The catch 134 is configured to contact and engage the step 126 on the first linear rack 111 in the extended configuration and disengage from the step 126 on the first linear rack 111 in the retracted configuration. To facilitate the engagement and disengagement of the catch 134 from the step 126, the step 126 may be angled or rounded, or a portion of the catch 134 facing the step 126 may be angled or rounded, or both.

As illustrated, the catch 134 is coupled to the bridge 119 through a pivot 135. The first latch mechanism 109 may also include a cantilevered spring 136 configured to apply a torque to the catch 134 about the pivot 135 to bias the catch 134 against the first linear rack 111. As illustrated, the cantilevered spring 136 may be integral to and extend from the catch 134. Accordingly, the cantilevered spring 136 may be configured to slide through one or more guide points 137 of the bridge 119, which constrain an end of the cantilevered spring 136 opposite the catch 134.

Operation of this example latch mechanism is substantially as described above for FIGS. 2-8.

FIG. 13 is a close-up of a portion of an alternative arrangement for the game controller 100 of FIGS. 5 and 6, illustrating an example latch mechanism in an unlatched configuration. FIG. 14 is a close-up of a portion of an alternative arrangement for the game controller 100 of FIGS. 5 and 6, illustrating the example latch mechanism of FIG. 13 in a latched configuration. While illustrated and described for the first-handle side of the game controller 100, the discussion for FIGS. 13 and 14 applies equally to the second-handle side of the game controller 100. Hence, the example latch mechanism of FIGS. 13 and 14 may be the first latch mechanism 109 described above for FIGS. 5 and 6, the second latch mechanism 110 described above for FIGS. 5 and 6, or both the first latch mechanism 109 and the second latch mechanism 110.

As illustrated in FIGS. 13 and 14, the example latch mechanism may include an elastic body 138 coupled to the bridge 119. The elastic body 138 is configured to contact and frictionally engage a raised portion 139 on the first linear rack 111 in the extended configuration and disengage from the raised portion 139 in the retracted configuration. To facilitate the engagement and disengagement of the elastic body 138 from the raised portion 139, the raised portion 139 may be angled or rounded, or the raised portion 139 may be angled or rounded, or both. As illustrated, the elastic body 138 is configured to elastically distort when engaged with the raised portion 139 of the first linear rack 111.

Accordingly, in transitioning from the retracted configuration (an example of which is illustrated in FIG. 13) to the extended configuration (an example of which is illustrated in FIG. 14), the first linear rack 111 slides relative to the elastic body 138 until the elastic body 138 contacts the raised portion 139 of the first linear rack 111. The elastic body 138 then elastically distorts and frictionally engages the raised portion 139 on the first linear rack 111. Likewise, in transitioning from the extended configuration to the retracted configuration, the elastic body 138 is disengaged from the raised portion 139 of the first linear rack 111. Otherwise, operation of this example latch mechanism is substantially as described above for FIGS. 2-8.

FIG. 15 is a close-up of a portion of an alternative arrangement for the game controller 100 of FIGS. 5 and 6, illustrating an example latch mechanism in an unlatched configuration. FIG. 16 is a close-up of a portion of an alternative arrangement for the game controller 100 of FIGS. 5 and 6, illustrating the example latch mechanism of FIG. 15 in a latched configuration. While illustrated and described for the first-handle side of the game controller 100, the discussion for FIGS. 15 and 16 applies equally to the second-handle side of the game controller 100. Hence, the example latch mechanism of FIGS. 15 and 16 may be the first latch mechanism 109 described above for FIGS. 5 and 6, the second latch mechanism 110 described above for FIGS. 5 and 6, or both the first latch mechanism 109 and the second latch mechanism 110.

As illustrated in FIGS. 15 and 16, the example latch mechanism may include one or more resilient clips 140 on the first handle 101. As illustrated, the resilient clip 140 may be within the guide portion 113 of the first handle 101. The resilient clip 140 is configured to contact and engage an outer edge of the bridge 119 in the extended configuration and to disengage from the outer edge of the bridge 119 in the retracted configuration. To facilitate the engagement and disengagement of the resilient clip 140 from the outer edge of the bridge 119, the resilient clip 140 may be angled or rounded, the outer edge may be angled or rounded, or both. The resilient clip 140 is biased against the outer edge of the bridge 119. As illustrated in FIG. 15, the resilient clips 140 may be disengaged from the outer edge of the bridge 119 while still being in contact with the outer edge.

As illustrated in FIG. 16, the resilient clip 140 engages a terminus of the bridge 119. In other embodiments, the resilient clip 140 may engage an indentation or step on the outer edge of the bridge 119, the indentation or step not being at the terminus of the bridge 119.

Alternatively, one or more resilient clips 140 may be on the bridge 119 and be configured to contact and engage the first handle 101 in the extended configuration and to disengage from the first handle 101 in the retracted configuration.

With specific reference to the embodiment illustrated in FIGS. 15 and 16, in transitioning from the retracted configuration (an example of which is illustrated in FIG. 15) to the extended configuration (an example of which is illustrated in FIG. 16), the bridge 119 slides relative to the first handle 101 until the resilient clip 140 engages the terminus of the bridge 119. Likewise, in transitioning from the extended configuration to the retracted configuration, the resilient clip 140 is disengaged from the terminus of the bridge 119. Otherwise, operation of this example latch mechanism is analogous to what is described above for FIGS. 2-8.

FIG. 17 is a top, perspective view of the game controller 100 of FIG. 1 in an example of a retracted configuration of the game controller 100 and illustrated next to an example mobile device 199. FIG. 18 is a top, perspective view of the game controller 100 of FIG. 17, in an example of an extended configuration of the game controller 100 and illustrating how the example mobile device 199 fits into the game controller 100 in configurations. As illustrated in FIGS. 17 and 18, the game controller 100 includes the first handle 101, the second handle 102, and the bridge 119, each as discussed above. The configuration illustrated in FIGS. 17-23 may include any or all of the features discussed in this disclosure for other configurations of the game controller 100.

In current models of mobile devices, such as the example mobile device 199 illustrated in FIGS. 17 and 18, the mobile device 199 has one or more speaker access holes 141 and one or more microphone access holes 142, and these are often at the same end of the mobile device 199 as the connector port 143. The speaker access holes 141 allow sound generated by the mobile device 199 to emanate from the mobile device 199. The microphone access holes 142 allow sound generated outside of the mobile device 199, such as the user's voice, to travel to one or more microphones located within mobile device 199.

As illustrated, the example mobile device 199, once fitted into the game controller 100, is positioned such that a display 144 of the mobile device is visible to a human user positioned to view the front side of the game controller. While the game controller 100 may have a number of orientations in actual use, for purposes of this disclosure, the front side of the game controller 100 is the side shown in FIG. 24, the bottom side of the game controller 100 is the side shown in FIG. 22, the top side of the game controller 100 is the side shown in FIG. 25, and the rear side of the game controller 100 is the side shown in FIG. 23. Accordingly, the front side of the game controller 100 is normally toward the user's face during typical use of the game controller 100.

FIG. 19 is a detail view of the second handle 102 and mobile device 199 of FIG. 18. FIG. 20 is a partial, bottom-view cutaway of the second handle 102 and example mobile device 199 as defined in FIG. 19. FIG. 21 is a partial, front-view cutaway of the second handle 102 and example mobile device 199 of FIG. 18. As illustrated in FIGS. 19-21, configurations of the game controller 100 may include an acoustic waveguide 145.

The acoustic waveguide 145 may be, as illustrated, at the juncture of the second handle 102 and the bridge 119. The acoustic waveguide 145 is configured to redirect sound emitted from the mobile device 199, such as through the speaker access holes 141 of the mobile device 199, toward one or more of the front side of the game controller 100, the top side of the game controller 100, and the bottom side of the game controller 100. Arrows 146 in FIGS. 18 and 19 illustrate the approximate directions in which the acoustic waveguide 145 is configured to redirect sound. As used in the context of redirecting sound, “in a direction toward the user” means toward one or more of the front side of the game controller 100, the top side of the game controller 100, and the bottom side of the game controller 100.

In configurations, sound traveling toward the back side of the game controller 100 (meaning the side opposite to the front side of the game controller 100), may be reflected by a backstop portion 147 of the acoustic waveguide 145. Sound reflected by the backstop portion 147 of the acoustic waveguide 145 is redirected toward one or more of the front side of the game controller 100, the top side of the game controller 100, and the bottom side of the game controller 100. In configurations, the backstop portion 147 of the acoustic waveguide 145 is integrated with the guide portion 114 of the second handle 102.

Accordingly, sound emitted from the mobile device 199 is redirected toward the user (in typical use of the game controller 100) by the acoustic waveguide 145. In the reverse direction, sound coming from the user or near the user, such as the user's voice, is directed toward the microphone access holes 142 of the mobile device 199 by the acoustic waveguide 145. Consequently, in configurations the game controller 100 does not have its own loudspeaker because the game controller 100 is configured to direct sound waves from the loudspeaker. In addition, in configurations the game controller 100 does not have its own microphone because the game controller 100 is configured to direct sound waves toward the microphone of the mobile device 199. In configurations, the handle with the acoustic waveguide 145 (labeled as the second handle 102 in the illustrated configuration) does not have a loudspeaker, does not have a microphone, or does not have either.

Additionally, in configurations the game controller 100 does not have any holes or other internal passages whose purpose is to allow sound from the mobile device 199 to pass through the game controller 100 (or, specifically, the second handle 102) to reach the user (or for sound from the user to reach the microphone access holes 142 of the mobile device 199) because external surfaces of the game controller 100 (or, specifically, the second handle 102) are configured to direct sound waves from the loudspeaker (and also toward the microphone of the mobile device 199).

In configurations, the acoustic waveguide 145 includes an acoustic gap 148 between the second handle 102 and the mobile device 199. The acoustic gap 148 is configured to provide a pathway to channel sound from the mobile device 199 toward at least one of the front side of the game controller, the top side of the game controller, and the bottom side of the game controller. In configurations, in the same way the acoustic gap 148 is configured to provide a pathway to channel sound toward the microphone access holes 142 of the mobile device 199.

Preferably, the acoustic gap 148 has a gap width 149 between about 0.5 mm and about 4 mm. More preferably, the gap width 149 is between about 1.5 mm and about 3 mm. Even more preferably, the gap width 149 is between 1.75 mm and 2.25 mm. As illustrated in FIG. 20, the gap width 149 is the distance between the mobile device 199 and the acoustic reflector 152 (described below) at the location of the speaker access holes 141 of the mobile device 199. A gap width 149 outside of the preferred range may cause sound emitted by the speaker access holes 141 of the mobile device 199 to either be too attenuated (a smaller gap width 149) or too diffuse (a wider gap width 149). In each case, the sound may not be sufficiently directed toward the user.

In configurations, the second handle 102 includes a standoff protrusion 150. The standoff protrusion 150 is configured to maintain the acoustic gap 148 between the second handle 102 and the mobile device 199. The acoustic gap 148, at its narrowest, is the distance between a distal end 151 of the standoff protrusion 150 and the acoustic reflector 152 (described below). The acoustic gap 148, however, may widen toward a top portion 153 of the acoustic gap 148 or a bottom portion 154 of the acoustic gap 148, an example of which is illustrated in FIG. 21. In configurations, the connector 125, as discussed above, extends from the standoff protrusion 150.

In configurations, the acoustic waveguide 145 includes an acoustic reflector 152. The acoustic reflector 152 is configured to direct sound from the mobile device toward at least one of the front side of the game controller, the top side of the game controller, and the bottom side of the game controller. As illustrated in FIGS. 17-21, in configurations the acoustic reflector 152 defines one boundary of the acoustic gap 148, and the acoustic reflector 152 is positioned across the acoustic gap 148 from the speaker access holes 141 of the mobile device. In configurations, the acoustic reflector 152 is molded into the main body portion 106 of the second handle 102. In configurations, the acoustic reflector 152 may be or include an arcuate surface 155 whose center of curvature 156 is within the acoustic gap 148 or otherwise outside of the main body portion 106 of the second handle 102.

Aspects may operate on a particularly created hardware, on firmware, digital signal processors, or on a specially programmed general purpose computer including a processor operating according to programmed instructions. The terms “controller” or “processor” as used herein are intended to include microprocessors, microcomputers, ASICs, and dedicated hardware controllers. One or more aspects may be embodied in computer-usable data and computer-executable instructions, such as in one or more program modules, executed by one or more computers (including monitoring modules), or other devices. Generally, program modules include routines, programs, objects, components, data structures, etc. that perform particular tasks or implement particular abstract data types when executed by a processor in a computer or other device. The computer executable instructions may be stored on a non-transitory computer readable medium such as a hard disk, optical disk, removable storage media, solid state memory, RAM, etc. As will be appreciated by one of skill in the art, the functionality of the program modules may be combined or distributed as desired in various configurations. In addition, the functionality may be embodied in whole or in part in firmware or hardware equivalents such as integrated circuits, field programmable gate arrays (FPGA), and the like. Particular data structures may be used to more effectively implement one or more aspects of the disclosed systems and methods, and such data structures are contemplated within the scope of computer executable instructions and computer-usable data described herein.

The previously described versions of the disclosed subject matter have many advantages that were either described or would be apparent to a person of ordinary skill. Even so, all of these advantages or features are not required in all versions of the disclosed apparatus, systems, or methods.

Additionally, this written description makes reference to particular features. It is to be understood that the disclosure in this specification includes all possible combinations of those particular features. For example, where a particular feature is disclosed in the context of a particular example configuration, that feature can also be used, to the extent possible, in the context of other example configurations.

Also, when reference is made in this application to a method having two or more defined steps or operations, the defined steps or operations can be carried out in any order or simultaneously, unless the context excludes those possibilities.

Furthermore, the term “comprises” and its grammatical equivalents are used in this application to mean that other components, features, steps, processes, operations, etc. are optionally present. For example, an article “comprising” or “which comprises” components A, B, and C can contain only components A, B, and C, or it can contain components A, B, and C along with one or more other components.

Although specific example configurations have been described for purposes of illustration, it will be understood that various modifications may be made without departing from the spirit and scope of the disclosure.
